Configuring Mpls-Aware Netstream; Configuring Ipv6 Netstream Flow Aging; Flow Aging Methods - H3C SR6600-X Configuration Manual

The refresh frequency and the refresh interval can both be configured. The template is resent when either
of the conditions is reached.
To configure the refresh rate for IPv6 NetStream version 9 templates:
Step
1. Enter system view.
2. (Optional.) Configure the refresh
rate for IPv6 NetStream version
9 templates.

Configuring MPLS-aware NetStream

An MPLS flow is identified by the same labels in the same position and the same 8-tuple elements.
MPLS-aware NetStream collects and exports statistics on a maximum of three labels in the label stack,
with or without IP fields.
To configure MPLS-aware IPv6 NetStream:
Step
1. Enter system view.
2. Collect and export
statistics on MPLS
packets.

Configuring IPv6 NetStream flow aging

Flow aging methods

Periodical aging
Periodical aging has the following methods:
Inactive flow aging—A flow is inactive if no packet arrives for the IPv6 NetStream entry within the
•
period specified by using the ipv6 netstream timeout inactive command. When the inactive flow
aging timer expires, the following situations occur:
The inactive flow entry is aged out.
The statistics of the flow are sent to NetStream servers. The statistics can no longer be displayed
by using the display ipv6 netstream cache command.
When you use the inactive flow aging method, the cache is large enough for new flow entries.
Active flow aging—A flow is active if packets arrive for the IPv6 NetStream entry within the period
•
specified by using the ipv6 netstream timeout active command. When the active flow aging timer
expires, the statistics of the active flow are exported to NetStream servers. The device continues to
